If there are activities in a workflow process that do not modify any elements of the data container, do these steps need to have an incoming data connector? If not, can I still reference the data container from a previous activity in the workflow (just to display it)?

Thanks.

Even if there's no input dataconnector still the activity should be displayed. But if you 've a dataconnector from the previous activity and map it , the input container of the current activity will be populated from the output container of the previuos activity. I believe this will not do any harm.

Hi,

If you want to use the container value either to display or to change it from application then you need to use the either the same data structure and map the data connector or use another data structure and map the required fields from the previous activities with the new container elements.

If you donot use the elements of the data structure in teh activity then you dont need to specify the data structure in the properties of activity.

You can use the previous activity data in the subsequent activites by just mapping the enitire container or just the elements.

I hope this answers your question.

Cheers
Ved
